Hello Sonics,

Thank you for your query.

I have noticed that you are receiving these Kernel errors on RUT2XX_R_00.01.14.3 and RUT2XX_R_00.01.14.4 software versions.

Recently we have had a new firmware release: RUT2_R_00.07.01, Could you please try upgrading and check if the kernel errors reoccur?

Link for Firmware download: https://wiki.teltonika-networks.com/view/RUT240_Firmware_Downloads

However, if this would not solve the issue Could you please download the troubleshoot file and forward it to me via Private Message? In order to download the troubleshoot file please login to routers WEBUI and Navigate to System -> Administration -> Troubleshoot and click Download on the troubleshoot file.

Best Regards,

Dziugas

Hello Dziugas

Many thanks for your response. i did the upgrade to RUT2_R_00.07.01 and it was working for just 1 hour or so.  i than could just connect via ssh and it booted all 2-5 minutes. i took it home and now it reboots endless. factory reset also not possible.

i will do an RMA.
